Be it known that We, JOHN E.. Gein. and IRA A. (linnn, citizens of sheUnited Sintes, residing at Cambridge, in the county of Guernsey andSlate of Ohio, and Eyesville, in the county of Guernsey, Stale of Ohio,respectively, have invented certain new and useful Improvements inAutomatic Car-Stops and @aging Apparatus for Mines; and We do herebydeclare the following to be a full, clear, and exact description of ktheinvention, such as Will enable others skilled in the art to which. itappertains to make and use the same,

0111' invention relates to mining appliances but has reference moreparticularly to automatic cer-stops and cuging-apparaius employed forelevatingy coalto the surface of mine shafts.

The object of the invention is to provide mechanismfor automaticallyreleasing @he irstand each succeeding one or" a train of loaded cars,delivering the saine upon the floor of a mine cage, elevating it'to thesurface, and finally discharging. theempy cars after they have beenreturned to the bottom of the "sh-aft. v

A. 'Eurher object is that of reducing ihe number'o employees required,safeguard ing Jrhe lives and limbs, or" those actually engaged in theseveral operations aforesaid,

and reducing operating expenses.

nJl/"ith these and other objeccs in vier.y our invention consists incertain novel featuree and in certain combinations and arrangewhieliwill be liereinafer de lowing.

By ret erence to Figs. 5 and 6, more especially, it

3 will be noted that the end rail sections 15, 7 15, arehinged toplatform 14 at their extreme outer ends as at 18, are connected at theirinner ends b a' cross bar 19 from which depend'hea ed bolts -or tie-rods20, connected reciprocally With a sub-frame of the cage of which adescription will follow. The said bolts 2O are surrounded by coilsprings 21, 21, which when compressed serve to elevate the innermost ,orfree ends of rail sections 15, 15 as shown by dotted lines in Fig. 5.Then normally depressed as represented by Figs. 5, 6 and 7 the said railsections are securely retained by a keeper 22 depending from the centerof cross bar 19, and a spring-pressed horizonally slidable latch 23carried by the underside of the licor or platform 14. To the downwardlycurved tail-stoel( of said latch 23 is a horizontally and outwardlyextend- 25mg operating link 24 the latter pivotally connected to a shortlever 25 carried by a' rockshaft 26, also journaled beneath the cagefloor, while-the opposite end of shaft 26 isvupwardly curved; or rigidlyconnected to a member upwardly curved in the path of a wheel traversingthe adjacent track section 15, this forthe purpose of automaticallywithdrawing latch 23 as a car leaves and permitting the track sectionsto assume their dotted position for purposes which will appear inconnection with a statement of operation hereinafter.

Rlgidly secured to, and downwardly extending from, the longitudinal siderails or channel irons 11, 11`` the mine cage, are

bolts 27 headed at 'their lowermost ends, upon which are reciprocallysuspended a sub cage-frame of skeleton form comprisH ing longitudinallyarranged side channel irons 28, 28, corresponding with the said irons11, 11 immediately above, and reinforced by transverse connecting irons29 bolted thereto at intervals as best shown by Figs. 5 and 6. Crossingat right angles go the said sub-frame members or irons 29 in socontinuous track across said hoor.

vertical alinement with slots 17, 17 of the ,cage floor 14 and ot alength to correspond therewith, are I beams 30, 30, upon the uppersurfaces whereof are secured rail sec V55 tions 31, 31 which aretherefore vertically movable upon the sub-frame with relation to thecage licor, and are adapted when elevated through slots 17, 17 toregister with the end sections 15, 15 and 16, 1G to make a iVhile atboth sides of the mine cage downwardly projecting V shaped strut rigidlysecured at its opposite endswith its inverted apex terminating at apoint below the lower- (5 most or normal position of the sub-frameaforesaid as shown by Fig. 2. At their lowermost points these struts areconnected by a cross bar 33 upon which is mounted an. enlar ed sleeve 34for purposes hereinafter statedi. .f

Leading to the mine shaft so as to regisl ter at times with the tracksaforesaid upon the elevator cage floors are a pair of tracks 35, 35 and36, 36 of ordinary construction but slightly inclined toward the sump.At a given point upon each track 35 and 36 approximately one car lengthfrom the sump are located ear stops of novel construction and operation,these also being coun-- terparts one of the other and adapted to thefirst ear of a train previous to caging same. These stops of which butone will be described, comprise a main rod or bar 37 having an adjustingnut 38 upon the lower end swiveled upon one of the ordinary trackcrossties, as best shown by Fig. 9. Upon said rod 37 is reciprocallymounted a hollow body member or vstop-block 39 having an upwardlyprojecting WedgeLshaped spur 40 for engaging, at times, the advancebumper of a coal caras shown by Fig. 2, while in terposed between thelower end of said block 39 and an adjusting nut 41 threaded upon theupper end of bar 37 is an absorption spring 42 tor reducing the shockwhen a car is suddenly arrested. To the uppermost portion of the saidstop-block 39 and upon each side thereof are pivotally connected adouble toggle lever 43, 43 .having their opposite or lower ends keyedupon a rock shaft 44, and' so positioned that the links of said togglesslightly pass their centers of attachment when elevated, as shown byfull lines. To both ends of said shaft 44 are also securely keyed oicrating levers 45, 45, from the free ends otIL which in a, horizontaldirection project pivotally connected rods 46, 46 which at theiropposite ends are again pavotA ally connected to bell-crank levers 47,47 journaled as at 48 in lixed supports or journal bearings uponopposite sidesof the track as indicated by Fig. 1` of the drawings. lltwill thus be seen that the'shorter members of the said bell-crank leversare located upon the inside, adjacent to the track rails, and in a'position to be engaged by th wheels of a passin 'car to rock saidlevers' upon their pivota supports.

Upon the same pivots Aor wrist pins 49, which serve to connect the upperend ot levers 47 and theircnperatiug rods 4G as aforesaid, are slidablysecured links 50 ter initiating in horizontal rods 51 leading to anupright 52 at one side of the elevator or cage shaft. As bestillustrated by Figs. 1 and 2 thc-said rods 51 at their-'outer ends arepivotally connected to the lower extremity of'` a T shaped tripper-oroperating member 53,-' which inturn is pivotully connected, as daicurely spiked l ,delivery t0 the mine or enges, an
